False news often spreads via public groups, or chats, with potentially fatal effects. The Security Service of Ukraine said in a tweet that it was able to effectively target Russian convoys near Kyiv because of messages sent to an official Telegram bot account called "STOP Russian War." In the past, it was noticed that through bulk SMSes, investors were induced to invest in or purchase the stocks of certain listed companies. Perpetrators of such fraud use various marketing techniques to attract subscribers on their social media channels. In 2018, Russia banned Telegram although it reversed the prohibition two years later.
